Nostalgia is a fond longing for the past that has been shown to increase feelings of meaning, social connectedness, and self-continuity. Although nostalgia for personal memories provides intra- and interpersonal benefits, there may be negative consequences of group-based nostalgia on the perception and acceptance of others. The presented research examined national nostalgia (a form of collective nostalgia), and its effects on group identification and political attitudes in the United States. In a sample of US voters (N = 252), tendencies to feel personal and national nostalgia are associated with markedly different emotional and attitudinal profiles. Higher levels of national nostalgia predicted both positive attitudes toward President Trump and racial prejudice, though there was no evidence of such relationships with personal nostalgia. National nostalgia most strongly predicted positive attitudes toward president Trump among those high in racial prejudice. Furthermore, nostalgia's positive relationship with racial prejudice was partially mediated by perceived outgroup threat. Results from this study will help us better understand how the experience of national nostalgia can influence attitudes and motivate political behavior.

怀旧是对过去的一种美好的向往，已经显示出可以增加意义，社交联系和自我连续感的感觉。尽管对个人记忆的怀旧可以提供人际和人际关系的好处，但基于团体的怀旧可能会对他人的感知和接受产生负面影响。本研究调查了民族怀旧（一种集体怀旧）及其在美国对群体认同和政治态度的影响。在美国选民的样本中（ñ= 252），个人和民族怀旧的倾向与明显不同的情绪和态度有关。较高的民族怀旧情绪预示着对特朗普总统的积极态度和种族偏见，尽管没有证据表明这种与个人怀旧情绪的关系。民族怀旧最强烈地预示着种族偏见高涨的人对特朗普总统的积极态度。此外，怀旧与种族偏见的积极关系部分由感知到的外来群体威胁来调节。这项研究的结果将帮助我们更好地了解民族怀旧的经历如何影响态度并激发政治行为。
